Political instability has existed in the regions where there is oil for years so don't give me that line.
What we have heard since the first of the year to justify the increasing price of oil is the following (not an exhaustive list by any means):
1. Terror premium
2. Increased demand in developing nations
3. Refinery outages due to fire
4. Concerns about supply
5. Weak dollar and oil as a hedge
6. Instability in oil producing nations
7. OPEC stating it would not increase production
Now I have a hard time figuring out how the increased demand in developing nationa has driven the cost up since January from the $85-90 range to $135 today. Plus, developing nations are not as rich as the US, so excepting for government subsidies, how can such nations afford the dramatic increases we have seen here?
Speculators (i.e. hedge funds and investment banks) have driven the price up. It is a self fulfilling prophecy when they say they expect $4 gas and whadda know - we do! Price at the station by my work has gone up $.21 since last Thursday. That is not supply and demand when demand is down over the last few months according to the government. Funny, at the same time inventories are down unexpectedly.
I see this as the same bubble we have seen in tech stocks, energy crisis in the west in 2000, housing bubble. A sudden and dramatic run up in price without regard to fundamentals.
The best way to deal with this is to increase the margin needed to hold oil. Right now it is quite low. Bump the margin up and you should see some speculators get out.
